A channel shaped carrier 23 is arranged under theforward arm of the ejector 23 and has ears 23 intermediate its endspivotally secured to the ejector by a horizontal pivot vpin 33. Thefinger 21 is fixed to the forward part of the carrier 23 to be supportedand shifted by the carrier. The nnger 21 is shaped and mounted to besubstantially-parallelwith the finger 23. A yoke 3i is provided on theouter or rear end of the carrier 23 and straddles the pin 23. A coiledspring 32 is arranged on the pin 23 to be under compression Y betweenthe Ayoke. 3| and the Vunder side of the ejector 23. During certainphases of the operation the spring 32 urges or pivots the carrier 23 'tocause the finger 21 to grip upwardly against Y the under sides of thecup beads Y.

The plunger 15 isengageable with the uppermost protruding -cup X and its downwardmovement subjects the nest or stack of cups X to a slight compressionand 21 with the bead Y holds'the cup X against vertical movement soVVthat the cup is stripped from the Vdie C when thelatter moves upwardlyat operation l0.

With the cup forming machine in operation the dies A to F, inclusive,perform the cup shaping downward movement of theejector 20'moving theejector to position OinFig. 6 where the cup X is entered'in the receiver`44. The downward movement of die B to its initial position alsoresults'yin compression" ofthe-"spring 33 so Vthat thecarrier 23 is`pivotedand ,the nnger 21 -is retracted to free the cup bead Y. Duringing and bead forming operations outlined above and the cams 4| Aand 42are continuously operated to control the ejector 20. The operation ofthe cup ejecting and counting mechanism of the invention considered inconjunction with operation i11 the ca'm surfaces 4Id and 42l'are vincooperation with' the roller 40 toV hold the ejector 20 in itsextended'position and immediately following operation 11' the surfacesIle and 42 act on the roller 40 to swing the ejector the general seriesof die operations outlined above y is as follows: When thedie B ismovedup against the die A at operation 2 the cam faces 4|* and 42 areengaging the roller 40 so that the ejector 20 is held in its retractedpositionl and the upward movement of the die B is accompanied by Aupward,movement of the ejector 20 under the action of the expanding spring 33.When the die B moves down a short distance to free theY cup blank atoperation 3 the ejector 20 is shifted downwardly a short distance and isbrought to the horizontal plane whichwill be occupied by Y the bead Y ofthe completed cup X. During i these operations2 and 3 suiiicientcompression is maintained in the' spring 33 to hold the gripping ejectorfinger 21 in the down or released position and the ejector 20 remains inits retracted position, the dwelling surfaces 4I and 4la of the camsremaining in cooperation with the roller 40. During operation 4 when thedie C is moved downwardly to draw the cup blank fromrbetween the dies Aand B the plunger 15 is moved' downwardly as above described, and

.may engage against the previously ejected cupV i X in the event the cupis protruding from the receiver 44. lWhen the die F'moves upwardly to 20free of the cup X and back tothe position L 'of Fig. 6. The cam surfaces4I* and 42* retain the ejector 20 in position L or'in this verticalplane until the ejectorfis again swung inwardly at operation 8 of thenext cycle or die actions.

yThe cup ejecting means and cup assembling I and counting means V of theinvention operate in synchronism with the cup forming dies of theskilled in the art or fall within the scope of the iron the rim portionof the cup X at operation 6 the pawl 59 is operated as above describedto advance the Wheel 56.' YIn the event that the previously completedcup X constitutes the last cup of the counted assembly or stack in thereceiver 44 the advancement of the wheel 5S brings the pin 68 againstthe lug 61 to release the iingers 49 so that the entire group oristackof previously completed cups X is dischargedVv from the receiver. Duringdie operation 7 the ejector 20 remains in its retracted position in theplane to be occupied by the cup bead Y. When the dies E and F separatetopositions suol. as indicated in Fig. 6 the cam faces 4lb and 42b acton the roller to shift the ejector 20 fromvthe retracted position abovementioned to the position M of Figs. 1 and 6 where the fingers 26 rand21 are ready to grip the bead Y. Duringrthe die operation 9 when thedies F and D move downwardly the compression on the spring 33 isrelieved and the gripping ejector finger 21 is actuated by the spring32. This bringsthe finger 26 into engagement with the under side of thebead Y and the bead is clamped between the fingers 26 and 21. Fig 3 ofthe drawings illustrates the positions of the dies at this time andshows the fingers 26 and 21 gripping the bead Y. The engagement of theejectorV fingers 2B following'claims. l
